Topics Learning Goals
Materials
Gravity & Mass Wasting





Glaciers & Ice Ages






Wind & Deserts








Groundwater









Running Water & Watersheds





Waves & Shorelines
-Define Mass Wasting and understand its role as often the first agent of erosion to act on newly weathered rock
-Explain the classification system for types of mass wasting describing 1 example of fast and slow
-Discuss controls and triggers of mass wasting
-Name and describe landscape features created by mass wasting

-Differentiate between continental and alpine glaciers in terms of characteristics
-explain how ice flows and transports sediment
-Describe how scientists discovered that ice flows
-name and describe the formation and appearance of landscape features (both erosional and depositional) that are created by glaciers
-understand the causes of glaciation
-describe the effect of the last ice age on New England's landscape

-Give an accurate definition of a desert and dispel myths about deserts
-Understand the role of water as an erosional agent in the deserts and contrast to humid regions
-discuss erosional and depositional features typical to desert environments
-Describe the conditions necissary for effective wind erosion
-Explain how wind erodes and transports, and deposits sediment & the features it creates

-Describe the zones of groundwater and its role as a reservoir of fresh water for humans, streams, lakes and plants
-Explain how groundwater flows including the concpets of porosity and permeability and the factors that affect them
-Describe how groundwater transports mineral material and contrast this to other agents
-Name and describe the formation and appearance of landscape features (both erosional and depositional) created by groundwater


-Identify the components of a watershed/river system & sources of water for them
-Describe stream flow including calculating the discharge rate of a stream given the necissary data
-describe how running water transports material and the features of erosion and deposition it creates in the landscape

-Identify the parts of a wave, how they are created and how they move
-Describe how waves erode, transport and deposit sediment including an understanding of the concepts of beach drift/longshore currents and wave refraction
-Name and describe the formation and appearance of landscape features (both erosional and depositional) created by waves
-Explain and evaluate different engineering solutions designed to deal with beach erosion
